- provements in Spring Suspensions, of which the following is aspecification.

Our invention relates'to spring suspensions of the type disclosed inapplication for United States Letters Patent, Serial No; 383,189,wherein the spring and the vehicle body or other related parts areconnected by flexible 1inks Which are rigidly secured at their oppositeends and which are so constituted *as to permit perfect freedom ofspring action While controlling-side sway and other objectioneblemovements.

The objects of our invention are to provide simple 21nd practical meansfor enabling the attachment anduse of suspension means of this characterwith vehicles new on the market and ineveiqy day use. i

In the accomplishment of these objects We have devised various forms ofattachment devices capable of ready application to the forms oi vehiclesprings used with different makes or" cars.

In the accompanying drawings we have illustrated 21 number of difi'erentforms the invention may take, but wish it understood that furthermodifications may be made without departure from the true spirit andscope of the invention as hereinafter defined and claimed.

. Ford car. The bracket 26 being of a size to fit the forward frontspring it will be evident that this makes it possible to substitute thisimproved Form of link suspension in place 01 the usual Ford rigid linksuspension by simply attaching brackets 26 to the ends of the frontspring and replacing the usual shackle posts with our special clampsupporting posts 3?. In making this change the bolt 29 may be the samebolt which was formerly used for the connection of the rigid suspensionlinks at the ends of the front spring and the auxiliary securing bolts--may be taken from the clips ordinarily used on the spring and whichbecome unnecessary when the channel brackets 26 are applied. since thesebrackets may overstand the second leaf. as We have indicated, and henceoperate in the capacity of spring clips.

The form of rear spring connection shown in Figs. 3 and 4c is generallysimilar to the front spring connection, thcmain difference being thatthe clamp carrying post 38 is provided with a horizontal boltextension39 instead of the Yertical bolt extension shown, to lit a correspondinghorizontal seat on the rear axle housing.

in Figs. 5 and. 6 'WGllfiVQ illustrated a connection for the rear end ofa semielliptic rear spring. The spring attached bracket and clampconstruction is generally similar to that first described and the onlypractical diii'erence is that in this casethe attachment bracket for theopposite end ofthe link is provided with cars a l pierced to receive theshackle bolt 4-2 at the rear end of the side sill 43 of the frame saidbracket also having an extension 44 in rear of the bolt 42 forming alever bearing against the inner curved face of the sill member andordinarily secured by a rivet or bolt fastening 4-5.

The construction illustrated in Figs. 9 and 10 is generally similar tothat last described but in this particular instance it will be notedthat the leverage extension 44 of the "frame attachment bracket 40overlies the top orouter side of the frame member 43. this on account ofthe fiat angle of the rear end oi the member.

For the connection of the rear ends of front semiclliptic springs we mayuse constructions like tl: ,2 shown in Figs. 1 8, i142. and l5-li. i iteach of those instances there braclmt H3 which adapted to he screwed bybolts, i? to the sill "I being suitably snake of in the and 8 and 15 and16 the clamp 3 35 is directly carried by this bracket Whereas in theform shown in Figs. ll and 12 an attachment like that shown in Figs. 5and 6 is used embodying parts 4:0 and 4:4. and secured by a shackle bolt42.

For a three-quarter elliptic rear end suspension we may usea structurelike that shown. in Figs. 5 and 6, as illustrated in Figs. 19 and 20,the leverage ext-s... .ion 44 in this case being designed to bearagainst the inner end portion of the upper leaf spring 47 instead ofagainst a rigid frame member; Y

in Figs. 13 and 14: we have illustrated a form of attachment for thefront ends of front springs similar in general respects to theconstructions described except that in this case the clamps are disposedto hold the connecting link substantially horizontal and are providedwith cooperating bearing pads el8-49 standing in overlapping relationand bearing on opposite faces of the interposed intermediate portion ofthe link. The upper bracket is designed to be attached to the forwardend of the side frame member 43, being generally similar to the bracketsillustrated in Figs. 5, 9, 11 and 19 in that it has ears 41 to fit theforward end of the frame pierced to receive the forward shackle bolt 50.This bracket also in this case is shown provided with rearwardlyextending leverage projections 51 overlying the upper face of the sidesill and secured down by a bolt or rivet 52.

In Figs. 17 and 18 we have illustrated a form or front end connectionfor a rear scmielliptic' spring like the connection last described in.that the link is interposed between bearing surfaces to operate as acushion but differing from that form in that the clamps are arranged tosupport the link on a downward forward incline so as to adapt the sameto take the forward thrust of the spring occasioned by the propellingeffort of the rear wheel. The upper bracket member 53 in this case maybe a special bracket or the one which is provided on the car for theregular rigid-shackle.

In the platform type of spring suspianlsion a connection is used suchillustrated in Figs. 21, 22 and 23. The brackets 54, 55 which areattached to the longitudinal side spring and the transverse rear springs56 and 57 respectively are generally similar to the channel brackets 26already described ti clamp jaws 'ti .i an
